I found another image in which you see some more elements, however the quality of the photo is low, I tried to improve it and at the top appears a structure that appears to be a part of the fuselage.
Surely these images are screenshots taken from a video, video that I could not find on the web.
I ask if any of the users of this forum can locate it and share it here, so that they can view it carefully with the hope of being able to detect some other clue as to which plane they are working on.
thank !
